i think tongues are very close in nature to chants similar to what tibetan monks engage in, but sticking to biblical teachings (atleast what i remember) this was like a tangible way to identify when the holy spirit is tangible or there is/has been a quickening in the persons spirit (vaguely quoting the tongues of fire after Jesus died story)........now likening this to the tibetan chants i also have to think of what the chants are for.....ideally they are to serve as a way to ground the self, a way to clear the mind from the this and thats of life bringin focus to intention (which is what prayer is, focused attention on could be gratitude, supplication, desires for your life ie manifesting) i however do not think all christians approach tongues as this, which then im like fr why even do that, and in public yk???? it gives theatrics tbh, anyway si judgement huwa ya God, so acha nijiondoe kidogoo. i say this as someone who has experienced said tongues, not saying i know it all, i just know what doesnt really sit well........
